To all 'whom t may concern:

Be it known that I, JESSE C. KELLY, a citizen of the United States of America, and resident of Madison Place, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Hydrocarbon-Oil Vaporizers and Burners,` of which the following is a specification.

My invention relates to the class of burners intended to vaporize coal oil and to burn the vapors.

An object of my invention is a burner of the class described, that will afford a uniform supply of vapors at the ignition port.

Another object of my invention is an oil vaporizer and burner that may be readily installed in an ordinary coal stove.

Referring to the accompanying drawings, in which like parts are indicated by similar reference letters;

Figure 1 is a longitudinal sectional view of the fire pot of an ordinary coal range and a perspective view of a burner embodying my invention installed therein.

Fig. 2 is a longitudinal sectional view of a vaporizerv and burner embodying my invention.

Fig. 3, is a transverse central sectional view of the fuel admission valves and valve casing upon an enlarged scale.

Fig. 4 is a 'detail elevation of one of the vapor spreaders.

Fig. 5 is a sectional view taken upon line 5 5, of Fig. 2.

rIhe fuel such as coal oil, is to be stored in a tank which is elevated above the level of v my vaporizer and burner and is to be led thence by a fuel pipe A to the casing B of a check valve b, whence it passes to the casing- C of admission valvesc and c. From the valve casing C the fuel is led by pipes D D to vaporizing. pipe sections E and E. thence into vapor chambers G and G which have ignition ports g and g', which direct the vapors against the spreaders H and H which are suspended above the ignition ports.

Check valve b is seated by gravity over the end of fuel pipe A, and has a valve stem b', which is guided by a spider b2, so that the valve Z) may be raised by the inward flow of the coal oil, except when the pressure in the vaporizing pipe section is such as to overcome the pressure of the inflowing fuel, at which time the back pressure will seat the Letters Patent.

check valve b, and prevent the formation of air or vacuumpockets in the fuel pipe.

Each vaporizingpipe section consists of a vertical portion e and return bend c', a horizontal portion c2, which extends above the .vaporizing chamber G, and a U bend e which enters thevalve chamber G near its top so as to leave below the pipe c3 a sediment portion g2. y

Chamber G has a tapered top gr3 which surrounds the ignition port g and forms a seat for needle valve g* which has screw threaded connections with the bottom of the vapor chamber, and terminates in a square end g5 which may be engaged by a wrench for the purpose of regulating the position of the needle valve.

Spreader H is preferably circular in form and has a curved surface h which assists in spreading the vapors and carrying them into contact with the walls of the vaporizing pipe section. Spreader H is suspended from portion e2 of the pipe by a hook h so that it may be readily removed therefrom when it becomes coated with carbon. The pipe sections D D are preferably secured in a casing K, in which7 beneath the va'por chambers I preferably support sheets of asbestos m m located in shallow pans M M suspended within the casing. The casing is preferably of the shape shown in Fig. 5, in which the side walls converge toward the top. This permits the air to be drawn toward the burners and to be discharged through the opening K K2 in the top of the casing adjacent to the burners, where the oxygen may be picked up by the gas issuing from ignitionl ports gV g and projected therewith against spreaders H H to cause the mixture to burn with a blue iiame.

The vaporizer and burner embodying my invention may readily be installed in the fire pot of an ordinary coal range, by supporting the casing K upon the grate bars thereof and so that the vaporizinc: chambers G G come below the stove lids N and N', the fuel door of the range being removed and the V-fuel pipes D D extending through the fuel door space.

In operation:

y The valve c or c which controls the burner which is to be ignited, is opened slightly so that oil will enter the valve chamber and iow out of the' ignition port g on to the asbestos M M. The admission valve is then closed and the fuel upon the asbestos is ignited. The heat from this fire will vaporize the oil in the vaporizing chamber G. As soon as the oil in the vapor chamber has been vaporized the vapors Will burn with a bluish llame around the ignition port. lVhen this occurs the admission valve c is opened to an extent such as to get the height of flame desired at the burner. Then the heat from the flames of the vapors ignited at the ignition port will continue to vaporize the fresh fuel as it'reaches the vaporizing pipe section. Should the pressure in the vaporizing pipe section become so great as to cause the pressure in the pipe/section D to overcome the pressure in the fuel pipe A, the check valve B will be seated by its gravity and will thus prevent any vapors backing into the fuel pipe A, and thus Will prevent the formation of air pockets, which might otherwise flare up when they reach the ignition port and cause the extinction of the flame at that point.

What I claim is:

In an oil burner the combination of a vapor chamber having a tapered top, a central ignition port in the top, a needle valve extending adjustably through the base of the chamber adapted to close upon the ignition port7 a vaporizing pipe section entering the vapor chamber adjacent the top thereof and curving thence upward and having a horizontal portion extending over the ignition port, a spreader suspended removably from said horizontal portion of the pipe over the ignition port and adapted to direct the flames from the ignition port against the vaporizing pipe section, a fuel pipe connected with the vaporizing pipe section, and an admission valve in the fuel pipe section.

In testimony whereof I have hereunto subscribed myname this 17th day of May,

JESSE C. KELLY. Witnesses:
